ICD-10-CM Code G02

Valid for Submission

G02 is a billable code used to specify a medical diagnosis of meningitis in other infectious and parasitic diseases classified elsewhere. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code G02 might also be used to specify conditions or terms like african trypanosomiasis, candidal meningitis, central nervous system candidiasis, coccidioidal meningitis, coccidioides infection of the central nervous system, cryptococcal meningitis, etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G02:

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

• underlying disease, such as:
• African trypanosomiasis B56
• poliovirus infection A80

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

• candidal meningitis B37.5
• coccidioidomycosis meningitis B38.4
• cryptococcal meningitis B45.1
• herpesviral herpes simplex meningitis B00.3
• infectious mononucleosis complicated by meningitis B27
• measles complicated by meningitis B05.1
• meningoencephalitis and meningomyelitis in other infectious and parasitic diseases classified elsewhere G05
• mumps meningitis B26.1
• rubella meningitis B06.02
• varicella chickenpox meningitis B01.0
• zoster meningitis B02.1

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

• Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• African trypanosomiasis
• Candidal meningitis
• Central nervous system candidiasis
